Attilio

Of the father; possibly related to the grandfather

Derived from the Roman family name Attilius, which likely stems from the Latin 'atavus' or the Etruscan 'atta', meaning 'father' or 'grandfather'. It was a prominent name in ancient Rome, notably held by several consuls and a famous general. In modern times, it remains a distinguished choice in Italy, though it is quite rare in the United States.
